Embodiment 1

[0024] Example 1: see Figures 1 to 3 , a steel mesh leveling tool for bridge deck pavement, comprising: a rotatable crowbar for leveling the steel mesh sheet; a leveling tool, set on the steel mesh to be adjusted, for detecting whether the adjusted steel mesh is reach the design elevation; the leveling tool includes a leveling rod and a leveling rope, the leveling rope is arranged on the top surface of the leveling rod, and its two ends are respectively connected to the leveling rod through a fixing piece, and the leveling rope is in the Straight line state. The height of the leveling bar is the thickness of the bridge deck pavement protection layer. The leveling rod is hollow square steel.

[0025] The pivot rotatable crowbar includes a crowbar and a door-shaped bracket. One end of the crowbar is a gripping part, and the other end is a prying part. The head is fixedly connected with the pry bar through the connecting sleeve, and the cross bar of the door-shaped bracket is...

Embodiment 2

[0026] Example 2: see figure 1 with image 3 , a leveling method using the above-mentioned steel mesh leveling tool for bridge deck pavement, comprising the following steps: first, placing both ends of the leveling tool on a fixed design elevation point, and then using a fulcrum rotatable crowbar to move the The steel mesh in the area to be leveled is pried up, and the visual inspection leveling rope and the top surface of the leveling rod are in full contact and are on the same horizontal line, that is, the steel mesh here reaches the design elevation, and the supporting steel is welded to the steel mesh at the same time firm. According to the above method, all the steel mesh sheets in this area are adjusted to the design elevation. The lower ends of the supporting steel bars are set on the bridge deck.

Abstract

The invention discloses a leveling tool and leveling method for a bridge deck pavement reinforcing mesh. The leveling tool comprises a crow bar with a rotatable fulcrum and a leveling tool body, the leveling tool body comprises a leveling rod and a leveling rope, and two ends of the leveling rod are directly placed on a set scale height control point; the leveling rope is arranged at two ends of the top surface of the leveling rod, two ends of the leveling rope are connected with the leveling rod through a fixing part respectively, and the leveling rope is in a straight line state. By adoption of the leveling tool for the bridge deck pavement reinforcing mesh, the bridge deck pavement reinforcing mesh is leveled, a worker only needs to press the crow bar downwards through a holding portion of the crow bar, so that the crow bar upwards pries the reinforcing mesh, the leveling rope of the leveling tool located on the reinforcing mesh is completely in contact with the top surface of the leveling rod, when supporting steel bars are welded to the designed position of the reinforcing mesh, the worker holds the supporting steel bars conveniently to conduct positioning welding, welding is convenient, and the construction efficiency is improved. The leveling tool for the bridge deck pavement reinforcing mesh is reasonable in design, simple in structure, convenient to use and manufacture, and low in manufacturing cost.

Description

technical field [0001] The invention belongs to the technical field of bridge construction, and in particular relates to a leveling tool and a leveling method for bridge deck pavement reinforced mesh. Background technique [0002] The longitudinal bars and transverse bars of the bridge deck pavement steel mesh form a network structure, and the load it bears can be evenly spread and distributed, which improves the seismic and crack resistance of the reinforced concrete structure. During the construction process, the bridge deck reinforcement mesh needs to be welded and laid according to the requirements. When laying the above reinforcement mesh, it is necessary to adjust the reinforcement mesh to the middle of the bridge deck pavement layer and meet the thickness requirements of the protective layer. The usual method is to place concrete pads under the steel mesh. The concrete pads are fragile and difficult to ensure the design position of the steel mesh. Contents of the in...
